Recording medium for long-term data retention, recording method, and recording/reproducing apparatus

摘要

Provided are recording media, recording/reproducing apparatuses, and recording methods for use in long-term data retention. Recording medium information may be copied and stored in a new information zone in a data area. Accordingly, if medium recognition of a lead-in area and/or a lead-out area fails, a recording medium may be recognized using the data recorded in the new information zone.

主权项

1. A recording/reproducing apparatus comprising:
an optical pickup configured to irradiate light onto a recording medium to record data thereon; a memory configured to store information of ranges of a valid data area and a second information zone of a recording medium, which are obtained in advance by performing a test; and a control unit configured to allocate a non-recording zone adjacent to one of a lead-in area and a lead-out area in a data area of a target recording medium, to allocate an information zone at an inner side of the non-recording zone toward a center of the data area, based on the information stored in the memory, and to control recording medium information to be recorded in the information zone.
